How to Find Your Navistar Engine Serial Number

International Truck Serial Number Lookup

The engine serial number for Navistar engines can be found stamped on a pad on the block. Navistar keeps the location pretty simple. For engines that were built before 2000, that pad can be found on the left side of the block, just under the head-to-block parting line. For engines newer than that, the pad is on the right side of the block, between the oil cooler and the top of the block.

Engine

For most Navistar engines that were built after 1993, you will need more than just the engine serial number. You will also need the engine model, model year, horsepower rating, and torque rating, which can all be found on the emission label. The emission label is located on the top of the rocker cover or intake manifold.

The Importance of Your Navistar Engine Serial Number

Engine serial numbers are incredibly important when you have a heavy duty diesel engine. If you have a heavy duty diesel engine, you probably already know that they dont follow the Make-Model-Year formula that automotive engines do. An engine thats a particular model is not guaranteed to be exactly the same as another engine of that same model. Engine serial numbers are a surefire way to get a list of the exact parts that are in your engine.

Where Is The Engine Serial Number Located

Engine

When youre working on your engine and you go to order parts, well need to know your ESN so we can get that list of parts in your engine. This will guarantee that we get you the right stuff. The only additional thing we would need to know is if you have over-sized bearings, or have otherwise changed the engine specifications, as that would not be accounted for in the ESN.

If youre ordering your parts over the phone, you can just tell your salesperson your ESN. If youre ordering online, you will see thatsome product pageshave a field underneath the price where you can input your engine serial number when placing an order. If this field exists on a page, we will need your ESN. Even if you dont supply it when placing the order, youll still probably get a call or email from us asking for it. So, to get your order processed without delays, be sure to input it when you order.

It is essential that when compiling warranty claims or product and field reports, that the ISOVIN is quoted in conjunction with the identification data of the component affected.
International Standards Vehicle Identification Number
The International Standards Vehicle Identification Numbering (ISOVIN) system is based on the uniform car model designation system. This identifies the vehicle in a coded series of characters.
The ISOVIN is positioned in the following locations:
1. ISOVIN plate under the windscreen - Viewed through the windscreen aperture.
2. Body and option plate - Left strut tower.
3. Safety compliance plate - Left B pillar.
4. Stamping in the front floor panel under the front right seat.
ISOVIN Plate
The ISOVIN plate (1) is located under the windscreen and is viewed through the windscreen aperture and is attached to the dash panel assembly with unique rosette headed rivets.
ISOVIN Body Stamping
Important:
If the front floor panel assembly is to be replaced, the ISOVIN will be lost. Contact your local Road Traffic Authority prior to replacing the panel to obtain the correct procedure for renumbering the vehicle.
A replacement body shell assembly is stamped during manufacture with a unique ISOVIN that identifies it as a replacement part.
If an error is made to the ISOVIN stamping during manufacture, it is crossed out so that it remains legible and the correct number is stamped underneath.

The ISOVIN is stamped into the front floor panel under the right front seat. The ISOVIN (2) is visible by lifting the carpet flap (1).
Body and Option Plate

The body and option identification plate (1) is located on the left strut tower (2) and contains the following information:
Model
Combination of letters and numbers identifying the body style and the mechanical pack.
A listing of regular production option numbers can be found by referring to the latest spare parts information for the applicable model.
Body No
